To all lwhom it may conccm:

Be it known that I, ANNE J. KLUEVER, a citizen of the United Statesresiding at Lakewood, in the county of duyahoga and State of Ohio haveinvented a certaln new and useful Improvement in Heaters, of which thefollowin is a full, clear, and exact description, re'erence being had tothe accompanying drawings. l

. This invention relates to heaters anQl dryers and is directed more-particularly to a heater and dryer for use inconnection with printingpresses land the like.

The primary object of the present invention is to provide an electricheater which shall quickly and thoroughly dry the printed` material asit passes-through the press and thus prevent the inkon a printed sheetfrom backsetting on an adjacent sheet of printed material.

Another object is to provide a device 'of this character which shall becapable of directing the heat upon the material as it passes through themachine and dispel'and prevent the formation of static electricitythereon so that the material may be easily handled andl neatly piled.

Another object 1s to provide a heater and dryerv for accomplishing theforegoing results which shall be simple in construction, inexpensive tomanufacture, and which shall be capablewof emittin the required heat forlong continuous periods or intermittent service involving frequentheating and cooling of the heating element, without deterioration.

A still further object is to provide means for simultaneously breakingthe heater circuit when the press is stopped, thus avoid-ing thepossibility of burning or otherwise damaging the material which might bepassing the heater at the time the press is stopped.

With these and other objects in view, the inventionv consistsin thevarious novel features of construction or arrangement and combination,all of which w-ill be fully described hereinafter and pointed out in theappended claims.

In the accompanying drawing wherein I have shown certain illustrativeembodiments of m invention, Fig. 1 is an elevation of one orm oofpmyheater; Fig. 2 is a transverse sectional view taken 0n the line 2 2 of.Fig. v1; Fig. 3 is a. detail sectional view taken. on the line 3-3 ofFig. 1;'Fig. 4 is s an elevation of a modified form of heater;

sheet metal and provided with a back 2 and sides 3. Secured within thiscasing .and spaced from the back 2 is a partition plate 4 which isfastened to the sides 3 in any suitable manner as by means of bolts 5.The partition 4 and back 2 define a space therebetween as indicated at 6which is filled with a suitable heat insulating material 7 such asasbestos. A corrugated plate 9 is vplaced against partition 4. As shownin Fig. 2, the

. peripheral edges of the sides 3 of the casing are defiected over theedges of the corrugated plate 9 and partition plate 4, and in thismanner serve to secure these elements together.

The corrugated plate defines a series of longitudinal grooves 10 inwhich are fastened a plurality of supports 11 which `are adapted to suport a heating element indicated at 12. ach of these supports consistsof a sheet metal bracket 13 whlch is riveted to the corrugated late, andis provided with an insulating bus ing 14 which is capable ofwithstanding high temperature and also electrically insulatlng theheating element from said bracket.

Suitable insulated terminals 15, 15 are mounted in one end of thepartition late 4 and serve to secure each end of the eating element 12.These terminals are electrically connected with a pair of pins 16, 16which are electrically-insulated from the end of the casing 1 throughwhich they project. A separable connector block 18 is adapted to receivethe pins 16, 16 in the usualV manner and establish electrical connectiontherewith. A conductor 19 extending from the source of current supply tothe block 18 has connected'therewith, a 'suitable thereof which areexposed to the heat, so

preferably enamel the metal parte that the heat Waves will be reflectedrather than absorbed. The enamel also serves to securethe insulatingbushings 14. in the sheet metal. sup orts 13. l

Referring to igs: 4 and 5 it will be seen that I have shown a modifiedform of con' struction wherein indicates a suitable casin which hassecured therein a semicylin 1cal reflector plate 26. This plate ispreferably formed from a metal capable of receiving a high polish, suchas copper, so that efiicient radiation of the heat will be obtained froma heating element 27 supported therein by suitable transversely arrangedinsulating bars 28.l These bars are secured in position by suitablebrackets 29 which are fastened to the sides of plate 26 by bolts 30which extend through said plate and also through the heater casing 25and fasten said parts together. As shown in Fig. 5 the reflector plate26 is spaced from the casing so that heat insulating material indicatedat 31, such as asbestos, may be placed therein.

In practice a-heater of this general type is usually supported by asuitableV bracket vradiate on the fpress so that the heat therefrom isto the printedfmaterial as it passes through the press. This' may beaccomlished by arranging the heater above or beow the printed materialbut I preferably positionv a heater of this'type above the l printedmaterial so that the heat will be radiated directly to the printed sidethereof. vrlhe press is usually fitted with a gear i' shift lever 35such as shown in Fig. 6 and in order to prevent the operator fromstopping the press without breaking the heater circuit, I interpose aswitch, indicated 36 1n the heater circuit. This switch is connectedwith lever 35 through a pair of links 317-37, the inner ends of whichare slidably connected with each other and a spring 38 is interposedtherebetween. vThis connection permits the4 lever 35 to be moved a lgreater distance than the switch lever so thatp when' the operatorthrows lever 35 to a neutral position to stop the ress, the switch leverwill be disconnected rom its contact and the heater circuit broken. Whenlever 35 isrotated to operate the press, the switch will automaticallyclose and bring the heater in operation.

Having thus described my invention, what series of parallel grooves, andheating ele.

ments disposed within said grooves'.

i 3. In a heater of the character set forth, the combination with acasing, of a corrugated enameled reflector plate arranged withinvandspaced, 'from said casing, heat .insulating material interposed betweensaid reflector and casing, a plurality of heatin coil supports securedto said reflector, an

heating coils carried by said supports andv arranged in the corrugationsof said reflector.

4:. In a heater of the character set forth, the combination with acasing, of a partition plate arranged within said casing, a portion'ofsaid partition plate being spaced from said casing, heat insulatingmaterial cof interposed between saidV partitionv and casing, a reflectordisposed within said casing, a plurality of supports secured to saidreflector, and a heating coil carrledby said supports. Y

In testimony whereof, I hereunto affix my signature.
